Subject: hwmon: (ltc4282): Fix reset_history file permissions
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b3db91c3bfea69a6c6258fea508f25a59c0feb1a;p=thirdparty%2Flinux.git

hwmon: (ltc4282): Fix reset_history file permissions

The reset_history attributes are write only. Hence don't report them as
readable just to return -EOPNOTSUPP later on.

Fixes: cbc29538dbf7 ("hwmon: Add driver for LTC4282")
